Wake-up signal based control resource set adaptation and data channel rate matching

Abstract

Methods, systems, and devices for wireless communications are described. A network entity may provide an indication of which parts of a control resource set (CORESET) may be utilized for control information, and which parts may be utilized for data transmissions. For example, a network entity may communicate configuration information indicating multiple parts of a CORESET resource set to a user equipment (UE), along with an indication to monitor for a wake-up signal (WUS). During a wakeup occasion, the network entity may transmit a WUS to the UE. The WUS may indicate to the UE whether one or more of the parts of the CORESET may be active and may thus be utilized for the communication of control information. In response to receiving the WUS, the UE may monitor for a transmission of control information, data information, or a combination thereof, from the network entity.
